OPERATION INTRODUCTION
Using Relative Mode
Selecting relative mode causes the meter to store the present reading as a reference for subsequent measurements.
1. Press the "REL" button. The meter enters the Relative mode and stores the present reading as a reference for subsequent
measurements, and "REL" appears on the display as an indicator. The display reads zero.
2. When you perform a newmeasuement, the display shows the difference between the reference and the new measurement.
Tip: Press the "REL" button again. "REL" flickers on the display,
and the display shows the reference. Press the "REL" button once more, the meter will return to Relative mode.
3. Press and hold down the "REL" button for more than 1 second, the meter will exit the Relative mode and "REL" will disappear.
Note: The meter enters manual range when you enter the Relative Mode.
Data Hold Mode
Press the "HOLD" button to hold the present reading on the display, the symbol "
exit the Data Hold mode, press the button again, "
Manual Ranging and Autoranging
The meter defaults to autorange mode in measurement functions which have both autorange mode and manual range mode. When the
meter is in autorange mode, "AUTO" is displayed.
1. To enter the manual range mode, press the "RANGE" button. The meter enters the manual range mode, "AUTO" turns off, "MANU"
turns on. Each press of the "RANGE" button increases the range. When the highest range is reached, the meter wraps to the lowest
range.
2. To exit the manual range mode, press and hold down the "RANGE" button for more than 2 seconds, the meter returns to the
autorange mode.
MIN MAX Recording Mode
The MIN MAX mode captures and records the minimum and maximum values of all input values since this mode is activated.
In the MIN MAX mode, when the inputs go below the recorded minimum value or above the recorded maximum value, the meter records
the new minimum or maximum value.
To use MIN MAX recording :
1. Select the desired function and manual range.
2. Press the "MAX/MIN" button to activate the MIN MAX mode and the display shows the maximum reading, meanwhile "MAX"
appears on the display as an indicator. Note: For MIN MAX mode, autoranging is not available.
3. Press the "MAX/MIN" button to step through the minimum reading ("MIN" appears), the present reading ("MAX" and "MIN"
flicker), and the maximum reading ("MAX" appears), and so on.
4. To exit the MIN MAX mode and erase stored readings, press and hold down the "MAX/MIN" button for more than about 1 second, the
display will show the present reading.
Measuring DC or AC Voltage
1. Connect the black test lead to the "COM" terminal and the red test lead to the "
2. Set the range switch to the
measurement with the "SELECT" button.
3. Select autorange mode or manual range mode with the "RANGE" button. If you use manual range mode and don't knowthe
magnitude of the voltage to be measured beforehand, select the highest range and then reduce it range by range until satisfactory
resolution is obtained.
4. Connect the test leads across the source or circuit to be tested.
5. Read the display. For dc voltage measurements, the polarity of the red lead connection will be indicated as well.
Note : To avoid electric shock to you or damages to the meter, do not apply a voltage higher than 600V between terminals although
readings may be obtained.
